HMC512LP5/LP5E

v06.0114

MMIC VCO WITH HALF FREQUENCY OUTPUT

9.6 - 10.8 GHz

General Description

Features

Functional Diagram

The HMC512LP5 & HMC512LP5E are GaAs InGaP

Heterojunction Bipolar Transistor (HBT) MMIC VCOs.

The HMC512LP5 & HMC512LP5E integrate resona-

tors, negative resistance devices, varactor diodes

and feature half frequency and divide-by-4 outputs.

The VCO’s phase noise performance is excellent over

temperature, shock, and process due to the oscilla-

tor’s monolithic structure. Power output is +9 dBm

typical from a +5V supply voltage. The prescaler and

RF/2 functions can be disabled to conserve current if

not required. The voltage controlled oscillator is pack-

aged in a leadless QFN 5x5 mm surface mount pack-

age, and requires no external matching components.

Triple Output: Fo = 9.6 - 10.8 GHz

Fo/2 = 4.8 - 5.4 GHz

Fo/4 = 2.4 - 2.7 GHz

Pout: +9 dBm

Phase Noise: -110 dBc/Hz @100 kHz Typ.

No External Resonator Needed

32 Lead 5 x 5 mm SMT Package: 25 mm²

Typical Applications

Low noise MMIC VCO w/Half Frequency, Divide-by-4

Outputs for:

• Point to Point/Multipoint Radio

• Test Equipment & Industrial Controls

• SATCOM

• Military End-Use
